@iuvi Hi! BitTorrent is part of I2P's capabilities, as is self hosting sites or forums. Same for using IRC. So sharing files, chatting, etc are available. There are plugins that are included for use in the I2P Java software, and other I2P compatible plugins can be added to your router console. There is no specific app - these are all contained in the router software itself.
